1 Claim. 1

My invention relates to door stops, particularly to door stops of the type which in service rest freely upon a floor adjacent to the lower edge of a door to be held in open position. The weight or mass of the door stop is such that an elfective check against the unintentional closing of the door is provided.

Door stops of this type are ordinarily made of metal or other heavy substance, so that a device of reasonably small size or proportions possesses the weight necessary to give the device the desired utility.

If, as sometimes has been the case, a door stop of the sort here in mind is made of porcelain or pottery, it must be made relatively large and cumbersome, in order that it shall possess the requisite weight.

My invention consists in a particularly effective arrangement of a wedge element on this so called weight-type of door stop, whereby thedoor stop may be made of lighter material than metal, and withal may be made smaller in size, more economically, and of neater and more pleasing appearance. It is a prime object of the invention to provide a relatively small door stop which may be formed integrally of vitreous material, more especially of glass, in a simple molding procedure, and which, even though it be relatively small in size and relatively delicate in appearance, afiords perfect utility.

The invention will be understood upon reference to the accompanying drawings, in which:

Figure 1 is a view in plan from above of a glass door stop providing an exemplary embodiment of the invention;

Figure 2 is a view of the door stop in side elevation; and

Figure 3 is a view comparable with Figure 2, illustrating one of the several permissible modifications in the structure of the invention.

Referring to the drawings the door stop comprises a body of glass, including a main body portion 2, and a tapering body portionBeXtending outward therefrom. It will be perceived that the device is compact in structure such that it may be integrally formed in a simple glass-molding or pressing operation, whereby economy and uniformity of production are realized. The main body portion 2 is substantially greater in size and weight than the portion 3, and it will be understood that, whereas said body portion 2 is herein shown to be formed as a plain vertical cylinder having a semispherical upper end, it may be fashioned in any one of a wide variety of designs or figures of more artistic merit, without loss of its essential utility, and perchance with enhancement of the appearance of the entire device.

In service the device is positioned on the floor, beside the bottom of the door to be held in open position, with the tapering portion 3 directed toward the space between the floor and the bottom edge of the door. Then, by pressing the device toward the door, or by swinging the door toward the device, the tapering portion 3 is wedged between the bottom edge of the door and the floor. The wedging effect thus obtained, plus the effect of the weight of the body portion from which the wedge portion extends, is instrumental in providing the desired adequate check against door movement.

It will be noted that the upper inclined face of the portion 3 is provided with transverse serrations 4 that are integrally molded in the glass. These serrations serve to increase the security of the wedging effect with the bottom edge of the door.

Additionally, it is important to note that the bottom faces of both portions 2 and 3 extend in substantially common plane to rest flat upon the floor. Indeed, it may be said the tapering portion 3 of the device is continued rearwardly from its pointed end in a platform portion 6 that underlies the main body portion 2. The bottom face of this platform portion is provided with means for inhibiting or resisting any tendency for the device to slide upon the floor upon which it rests. Such means advantageously consist in serrations, or equivalent friction-augmenting elements, 5 integrally molded in the glass body. The serrations 5 (or the like) are especially effective upon a floor covered with carpet.

In modification the nether surface of the device may be faced with a layer of felt, or rubber, or like frictional material I, as indicated in Figure 3, and the device so constructed is eifective not only on carpet covered floors but on hard surfaced or slippery floors as well.

Within the terms of the appended claim many variations and modifications in the structural form of the door stop may be made by the artist or artisan without departing from the spirit of the invention, particularly I have in mind a wide variety of artistic shapes and figures in which the weight-affording body portion 2 may be fashioned and blended with the wedge portion 3.

I claim as my invention:

A door stop device comprising an integrally molded mass of vitreous material having a weightaffording body portion formed at its bottom with a relatively expansive basal area for laterally extended contact with a floor upon which the device is placed, and an integral tapered portion extending outward from said body portion and being relatively narrow with respect to said laterally extended floor-contacting area of said body portion and having a correspondingly diminished basal area'for contact-with said .fioor ata concentrated pressure point beneath the lowerslde edge of a door with which said tapered portion is wedged, whereby said body portion With'its laterally extended contact with the floor and said relatively narrow tapered portion provide an effective combination of laterally supported mass and concentrated wedging action to-secure said door against unintended movement.
